libsepol/cil: use __cil_ordered_lists_destroy() to free unordered_classorder_lists

Browse Source 
In cil_resolve_ast, unordered_classorder_lists is a list of
cil_ordered_list. It needs to be destroyed with
__cil_ordered_lists_destroy() to free all associated memory.

This has been tested with the following policy:

    (class CLASS1 ())
    (class CLASS2 ())
    (classorder (unordered CLASS1))
    (classorder (CLASS2))

This memory leak has been found by running clang's Address Sanitizer on
a set of policies generated by American Fuzzy Lop.
